I really don't care if Roy is in or not, but a Wolf was a completely original fighter and it would be a shame not to see him back. The easiest reveals and releases are obviously going tone the fighters they already have data for.
As for Ryu, I would be very pleased to see his inclusion, I think he would be a suitable candidate for a fighting game. I am not too keen on Inklings, though. They're not all-stars just yet.
